Abstract
The invention relates to a soil improver containing coconut chaff and a preparation method thereof, and relates to a soil improver. The soil improver containing the coconut chaff comprises the following components by weight percent: 0.75 to 0.92 percent of coconut chaff, 0.05 to 0.1 percent of diatomite, 0.01 to 0.05 percent of polyaspartic acid, 0.01 to 0.05 percent of humic acid, 0.005 to 0.03 percent of polyacrylamide and 0.005 to 0.02 percent of boric acid. The preparation method comprises the following steps: (1) dissolving polyacrylamide, polyaspartic acid and boric acid in water to obtain a mixed solution; (2) uniformly mixing powdered coconut chaff, diatomite and humic acid to obtain a solid powdered mixture; (3) spraying the mixed solution obtained in the step (1) into the solid powdered mixture obtained in the step (2), mixing, and air-drying to obtain the soil improver containing the coconut chaff. The production cost is low, raw materials are environmentally friendly and non-toxic, the secondary salinization and hardened soil can be effectively improved, and the productivity of the earth can be restored and improved.
Description
Technical field
The present invention relates to soil improvement agent, specifically relate to a kind of soil improvement agent containing coconut palm chaff and preparation method thereof.
Background technology
Secondary salinization is the salting of soil process caused due to irrational farming irrigation, excessively fertilising.The content of soil with organic matter is an important indicator of soil fertility and crumb structure, and organic reduction, causes soil compaction.China's agricultural arable area is limited, and in recent years, along with the using of a large amount of mineral manure, irrational irrigation and Development of China's Urbanization are accelerated, the artificial unreasonable measure factor impacts such as non-agricultural exploitation occupies cultivated land, the problems such as the sandstone, Secondary Saline and the soil compaction that cause city periphery to be ploughed are aggravated increasingly, there is the features such as low in high ph-values, high harmful salt content, poor air permeability, easily knot tying block, fertility, affect the normal growth of crop, cause the waste of agricultural resource and the destruction of ecotope.Therefore be necessary to carry out soil improvement, recover and improve the productivity in soil, this has important strategic importance to guarantee national food security and national ecological environment security.
Chinese patent application 201410163914.X discloses a kind of mineral soil soil improver, is composited according to a certain percentage with Wingdale, humic acid, diatomite etc.; But Rate of Humic Acid reaches 30%, and soil improvement agent usage quantity is large, and manufacturing process is complicated, causes that to use cost high.Chinese patent application 201310163404.8 discloses a kind of fertilizer of keeping soil from packing together and preparation method thereof, and NPK fertilizers and humic acid mixing granulation are obtained finished product.But this fertilizer of keeping soil from packing together, Rate of Humic Acid is very large, and cost is higher, and improved effect Industry Promotion application has certain limitation.
Summary of the invention
The object of the present invention is to provide production cost low, raw material environment-protecting asepsis, effectively can improve Secondary Saline and the soil that hardens, recover and improve a kind of of fertility to contain soil improvement agent of coconut palm chaff and preparation method thereof.
The described soil improvement agent containing coconut palm chaff consist of coconut palm chaff, diatomite, poly aspartic acid, humic acid, polyacrylamide and boric acid, each component is in mass ratio: coconut palm chaff 0.75 ~ 0.92, diatomite 0.05 ~ 0.1, poly aspartic acid 0.01 ~ 0.05, humic acid 0.01 ~ 0.05, polyacrylamide 0.005 ~ 0.03, boric acid 0.005 ~ 0.02.
The preparation method of the described soil improvement agent containing coconut palm chaff, comprises the following steps:
1) polyacrylamide, poly aspartic acid and boric acid are dissolved in the water, obtain mixing solutions;
In step 1) in, the mass ratio of described polyacrylamide, poly aspartic acid, boric acid, water can be (0.5 ~ 3): (1 ~ 5): (0.5 ~ 2): (90 ~ 98).
2) pulverous coconut palm chaff, diatomite and humic acid are mixed, obtain solid powder mixture;
In step 2) in, the mass ratio of described coconut palm chaff, diatomite and humic acid can be (75 ~ 92): (5 ~ 10): (1 ~ 5).
3) by step 1) mixing solutions that obtains is sprayed onto step 2) in gained solid powder mixture, dry after mixing, obtain the soil improvement agent containing coconut palm chaff.
The using method of the soil improvement agent containing coconut palm chaff of the present invention is: soil improvement agent 100 ~ 1000kg is used on every mu of ground, then plows and rakes the soil level, by soil improvement agent and mixing with soil even.
Coconut palm chaff is cocoanut husk fiber dust, and being the coconut by product after processing or waste, is the organic medium of a kind of pure natural under coming off from cocoanut husk fiber process, environmental friendliness and cheap.
Soil improvement agent containing coconut palm chaff of the present invention can improve Soil structure, increases soil organic matter content, and reduce the soil weight, make loosing soil and have crumb structure, what improve soil sees through ability, thus eliminates soil compaction, alleviates perniciousness harm.
Soil improvement agent producing process containing coconut palm chaff of the present invention is simple, and the economic environmental protection of starting material, low production cost, application process is simple, and reclamation result is good.
